Ecological surveys often extend beyond daylight hours, requiring tools to observe nocturnal wildlife effectively. Night-Vision Aids (NVAs) have revolutionised the way ecologists conduct surveys in the UK, enabling the exact bat emergence points to be pin-pointed, even in pitch blackness.

​

NVAs offer significant advantages:

​

• Superior Vision in Low Light: NVAs amplify existing light, allowing ecologists to see nocturnal animals with exceptional clarity, even in complete darkness.

• Expanded Detection Range: Spot elusive species, leading to more comprehensive data collection.

• Improved Roost Location Identification: Enhanced visibility allows us to remove uncertainty through accurate identification of roost locations/roost access points.

• Recording: Secure clear photographs for documentation purposes.

Complying with Regulations and Best Practices

​

The use of NVAs is included within the most up to date bat survey guidelines (Collins, 2023). Aven Ecology uses both infra-red and thermal imaging technology to ensure your surveys comply with best practice guidelines and legal requirements.
